AMC24MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC24MMSD is a 48-position male card edge connector manufactured by Sullins Connector Solutions, designed to interface with female edgecards at 0.100" (2.54mm) pitch. This connector features dual read-out configuration with gold-plated beryllium copper contacts and operates across a temperature range of -65°C to 200°C.

The AMC24MMSD is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and production requirements for legacy systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC24MMSD is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Male card edge connector
• Number of positions: 48
• Pitch: 0.100" (2.54mm)
• Read out configuration: Dual
• Contact finish: Gold plating
• Termination method: Solder
• Operating temperature range: -65°C ~ 200°C
• Insulation material: Polyphenylene Sulfide (PPS)
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Contact material (beryllium copper to phosphor bronze)
• Flange opening orientation (side opening to top opening)
• Card thickness specification
• Connector color
• Product status (obsolete to active)

The RMC24MMSD meets all mandatory matching parameters while introducing allowable variations in contact material composition and flange design. Both connectors maintain identical electrical and thermal performance specifications.

Parameter Comparison

Engineering Selection Recommendations

The RMC24MMSD serves as a direct functional substitute for the obsolete AMC24MMSD. Both connectors maintain identical electrical specifications, thermal operating range, and compliance certifications. The RMC24MMSD is currently in active production status, ensuring availability for new procurement and replacement applications.

The primary design differences between these connectors are the contact material composition (phosphor bronze versus beryllium copper) and flange opening orientation (top opening versus side opening). These variations do not affect electrical performance or thermal characteristics. Both connectors are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The RMC24MMSD is suitable for direct substitution in applications where the AMC24MMSD was originally specified, provided that the mechanical mounting orientation accommodates the top opening flange design.

Frequently Asked Questions (FAQ)

Q: Can the RMC24MMSD directly replace the AMC24MMSD in existing designs?

A: The RMC24MMSD is electrically and thermally equivalent to the AMC24MMSD. Substitution is valid provided the printed circuit board layout and mechanical assembly accommodate the top opening flange orientation of the RMC24MMSD, as opposed to the side opening design of the original part.

Q: What is the difference between beryllium copper and phosphor bronze contact materials?

A: Both materials are used in card edge connector applications and provide equivalent electrical conductivity and contact reliability. The contact finish (gold plating) and finish thickness (30.0µin) are identical on both parts, ensuring equivalent contact performance.

Q: Are both connectors compliant with current environmental regulations?

A: Yes. Both the AMC24MMSD and RMC24MMSD are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the significance of the dual read-out configuration?

A: The dual read-out configuration indicates that the connector accommodates two rows of 24 positions each, totaling 48 positions. Both the main part and substitute maintain this configuration.

Q: Does the flange opening orientation affect electrical performance?

A: No. The flange opening orientation (side opening versus top opening) is a mechanical design feature that affects physical mounting and assembly orientation only. Electrical performance and contact reliability remain equivalent.

Q: What is the moisture sensitivity level, and why is it relevant?

A: Both connectors have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control measures. This simplifies storage and handling requirements.
